REST API Setup Guide

Hevo allows you to bring data from various Sources through its native connectors. However, for situations where you need to fetch data from several applications or an in-house REST API, you can use the REST API connector.

The following image illustrates the key steps that you need to complete to configure REST API as a Source in Hevo:

REST API Source Setup


Limitations

  • By default, Hevo uses the __hevo_id metadata column as the primary key to load data from your REST API Source to the Destination. As a result, you may see duplicate data in the Destination if you have mutable data in your Source. To avoid this, you can set another column as the primary key.

  • Hevo accepts only JSON content type in the response from your REST API Source for the requests that it makes. If your Source API returns a response in any other type, such as CSV, you may see the HTTP Status: 406 error.

  • Hevo’s REST API connector does not support API chaining. In this technique, multiple API calls are used in sequence to achieve a specific task. The response of the last API call feeds the next call, and so on.

    For example, you cannot use the bearer token received in the response of the first API request to authenticate the subsequent API request.
